## Which is the another renowned nomenclature assigned to “Admittance Parameters” ?

a. Z parameters

b. Y parameters

c. h- parameters

d. ABCD parameters

Correct Answer : b. Y parameters

**Explanation :**

Admittance estimation is performed using Y-parameters which are determined by evaluating currents in terms of voltage at two ports. Thus, currents are dependent variables while voltages are independent variables in case of Y-parameters. Apart from these, Z parameters determine impedances, h-parameters are determined in terms of voltages & ABCD parameters assist in power transmission evaluation in terms of voltage gain, impedance, admittance along with current gain.
